Ymir's Personality

Ymir can be seen as selfish, cynical, blunt, sarcastic, and ruthless, but also loyal, compassionate, honest, and selfless. She is driven by her own survival and freedom, but also by her love and devotion to Historia. She is not afraid to speak her mind and challenge authority, but also respects strength and courage. She is willing to kill and betray others for her own benefit, but also to sacrifice herself for the sake of those she cares about.

Ymir’s personality is shaped by her tragic and traumatic past, which is revealed in flashbacks throughout the series. She was born in Marley, a nation that oppressed and persecuted the Eldians, the descendants of Ymir Fritz, the first Titan. She was taken in by a cult that worshipped Ymir Fritz and claimed that she was her reincarnation. She was given the name Ymir and treated as a goddess by the cult members, who gave her love and respect that she never had before. However, she was also exploited and manipulated by the cult leader, who used her as a tool to gain followers and money.

Ymir’s life changed when the cult was exposed and arrested by the Marleyan authorities. She was branded as a heretic and a traitor, and sentenced to be turned into a mindless Titan as a punishment. She was injected with Titan spinal fluid and pushed off a wall, where she transformed into a monstrous creature. She wandered the land outside the Walls for 60 years, losing her humanity and memories, until she encountered Reiner Braun, Bertolt Hoover, and Marcel Galliard, three Marleyan warriors who possessed the Armored, Colossal, and Jaw Titans, respectively. She attacked them and devoured Marcel, inheriting his Jaw Titan power and regaining her human form and consciousness.

Ymir’s second chance at life made her value her freedom and survival above all else. She decided to live for herself and do whatever she wanted, without caring about the consequences. She joined the 104th Training Corps, where she met Historia, who was hiding her true identity as the illegitimate daughter of Rod Reiss, the king of the Walls. Ymir recognized Historia’s situation and decided to help her, feeling a connection with her as a fellow outcast and liar. She encouraged Historia to be herself and not to live for others’ expectations. She also developed romantic feelings for Historia, which she confessed later on.

Ymir’s personality was tested when the truth about her past and her Titan power was revealed. She was forced to choose between staying with Historia and the Scouts, or joining Reiner and Bertolt, who were revealed to be the enemies who broke the Walls and caused the death of many people. Ymir initially chose to side with Reiner and Bertolt, hoping to find answers and a way to survive in the outside world. She also wanted to repay her debt to Reiner for saving her from a mindless Titan, and to Marcel for giving her his power. However, she soon realized that she had made a mistake, and that she belonged with Historia and the Scouts. She decided to return to them and fight against the Marleyan forces, even though she knew it was a hopeless and suicidal mission. She ultimately gave up her life and her power to Porco Galliard, Marcel’s younger brother, who inherited the Jaw Titan from her.
